German police reported that they have arrested a 27-year-old Syrian man on Wednesday for stabbing a 30-year-old psychologist and refugee aid worker to death during an argument. The stabbing took place in a Red Cross therapy and counselling centre in Saarbrücken, near the border with France. The suspect, who also injured himself, was arrested shortly after the attack and subsequently hospitalised.

The suspect had gotten into an argument with the victim, working with traumatised refugees, during a counselling session and stabbed him with a knife. The victim died of his injuries on the scene. The reasons for the conflict is still unclear, but police are ruling out terrorism as a cause.

German newspaper Die Welt reported that the psychologist, Musaab al-T., was himself an immigrant, having moved to Germany from Iraq in 2005. In an interview with the Saarbrücker Zeitung last year, he said “I was born and raised in war.” The victim had completed his Bachelor’s degree in psychology in Saarbrücken and was working on his Master’s Degree.

In reaction to the crime, German Red Cross president Rudolf Seiter said he was:

“Appalled and shocked. All of the German Red Cross mourns an admirable worker. Our sympathies are with his family members.“

According to another spokesman for the Red Cross, there is always a risk in working with people from war-torn countries. Red Cross Saarland currently has around 2,500 full-time employees and more than 6,000 volunteers working with the more than one million asylum seekers that have entered Germany since 2015, about half of whom are from war-torn Syria, Iraq and Afghanistan.
